I’ve previously covered the debate about whether the death star is a good investment from a fiscal point of view. Now the debate is about whether it is a good idea politically. The case against:
First, the Death Star is a bit misunderstood. It is primarily a tool of domestic politics rather than warfare, and should be compared to alternative means of suppressing the population of a galaxy. Second, as a weapon of war, it should be compared to alternative uses of scarce defense resources. Understood properly, the Death Star is not worth it. …
I see the Death Star (DS) as the Emperor’s solution to the dictator’s dilemma. First, note that its construction precedes the Rebel Alliance; the plans are first developed by the Separatists in Episode 2 and, by the time it is completed, the Rebel Alliance has just won its “first victory.” While it may have some use as a deterrent against possible invaders, the DS is primarily a tool of domestic politics. Prior to its completion, the Emperor is compelled to keep the Imperial Senate around, presumably to maintain the semblance of popular consent. But the Senate imposes some inefficiency—meddling in military strategy, perhaps, or directing spending to some favored planets. Once the DS is operational, the Emperor can disband the Senate and, instead, empower Imperial governors to suppress the local population and extract revenue.
So the Death Star was about allowing the Senate to be replaced by Governors.
But how can the Emperor guard against rebellion by one of these governors? Or revolt by a local planet’s population? The answer is simple: he can zip around in the baddest weapon in the galaxy, destroying his foes with the push of a button. No foe could fight back, and the DS is mobile enough to respond to multiple threats in short order.
Note that this scheme provides an easy answer to the question, “how can we afford a Death Star?” If the scheme works, the Death Star will pay for itself dozens of times in the additional tax revenue from fearful planets, and by the money not spent by the military putting down revolts with conventional weapons.
So seems a good idea, right?
But will it work? Only if it induces cooperation through fear. Every planet blown up represents a tremendous loss of potential future revenue, so like nuclear weapons today, the actual use of the DS is a calamity. Moreover, like nuclear weapons, they only work as a deterrent if they are used judiciously. citizens throughout the galaxy must believe that failure to pay their taxes and comply with their Imperial masters will lead to detonation, but also that compliance will save them. The fact that the DS was used against Alderaan, however, would likely have had the opposite effect. Alderaan is “peaceful” and “has no weapons.” It was detonated because its teenage senator was secretly aiding the Rebel Alliance and waited too long to give up Dantoonie. …
If the net effect of the DS is to make every person in the galaxy think their planet could be the next one arbitrarily destroyed, it actually mobilizes them to join the rebellion.
So use of the death star will not work, and indeed it did not.
